The Lowdown
Alright, let me break it down for you. This is Rusty, and I’m lookin’ at the local surf scene for Kennebunk Beach.
Well, I gotta be straight with you folks – the next 16 days are lookin’ mighty flat. We’re talkin’ about a long stretch of almost nothing to get excited about. The whole forecast is a bit of a bummer, honestly. The first recommendation we get is for a tiny, weak swell, and it’s all downhill from there.
The water is a touch warmer than normal for this time of year, sittin’ at 69°, but that’s about the only bright spot.
Let’s run through it. Startin’ Wednesday afternoon, we’ve got a tiny 0.3 ft swell from the SE with a period of 14 seconds, but the combined energy is a measly 17 – that’s barely a ripple. Winds are light onshore. Not worth wetsuitin’ up for.
Thursday the 13th sees a bit of a bump in the mornin’, with 3 ft from the SSW, but the period is a short 5 seconds, so it’ll be weak and choppy. The combined energy is only 43. The wind is glassy though, so it’ll be clean, but there’s just no power. By afternoon, we’re back to a 0.3 ft dribble.
Friday and Saturday are more of the same – tiny, weak swells, under 1 ft, with onshore or cross-shore winds. The energy is in the teens and twenties. It’s a waste of time, honestly.
Sunday the 16th afternoon gets a little interesting with a 5 ft swell from the S, but the period is a terrible 5 seconds and the wind is honkin’ at 16 mph cross-onshore. The combined energy is 92, which is still weak. The onshore wind will chop it up into a mess. Not a paddler’s day.
Monday the 17th and Tuesday the 18th offer a little hope with 3 ft and 2 ft swells, but again, short periods and mostly cross-onshore winds. The best of the bunch might be Monday mornin’ with a glassy 3 ft from the SSE, but that energy is only 36. It’ll be clean, but tiny and weak.
The rest of the week into the next is a blur of tiny 1 ft to 2 ft swells, short periods, and onshore winds. The energy barely cracks 60. There’s a moment on Sunday the 23rd with a 0.7 ft swell from the ESE and a 12-second period, but it’s so small it’s laughable.
The only real standout, if you can call it that, is Monday the 24th afternoon. We get a 4 ft swell from the S, and the combined energy jumps to 128 (moderate). The period is still a short 5 seconds, which means it’ll be a bit of a mushy closeout at a beach break like Kennebunk. The wind is cross-shore, so it won’t be clean. This is the biggest swell we see, but it’s not good. It’s the kind of day that might be more fun for a kite surfer than a paddler.
After that, we’re back to tiny dribbles and glassy conditions with no real swell. The 16-day window is a washout. This is Kennebunk Beach – it’s a sheltered spot, and when the swell doesn’t line up, it just doesn’t. Don’t hold your breath. Forecasts can change, but right now, it’s a flat spell.
Rusty.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
